Logan has been a purchaser of a hydraulic company in the United States for several years, and the purchasing of hydraulic valves in China is also very smooth. But recently, a high-precision hydraulic relief valve order worth more than $30,000 wasted him a lot of time. The original hydraulic relief valve manufacturer made the samples twice, but was still not approved by the customer. His customer understood that the original manufacturer was unable to meet the requirement of 0.3mm finish size allowance, and asked him to change the hydraulic relief valve manufacturer to make samples for the third time. If the hydraulic relief valve sample for the third time still cannot be approved, the customer can only cancel the order. This order attracted the attention of his boss, who asked him to solve the problem and get the sample of hydraulic relief valve approved at one time within 20 days.

 

Five days later, Logan consulted many hydraulic relief valve suppliers, and most manufacturers said that they could not meet the standard of 0.3mm finishing size allowance. Logan is a little worried. He looks for hydraulic relief valve manufacturers everywhere on the Internet. He left a message on our AAK website: how can we guarantee the finishing dimension allowance? All such messages are basically for difficult problems encountered in the purchase of hydraulic valves. After some communication, it is understood that the Logan was stuck on the sample approval process of the hydraulic relief valve order, and he has contacted many hydraulic relief valve manufacturers, but no solution has been obtained.

 

I suggested Logan try our sample directly, and let the test data to speak for itself and this also saves time.  Logan doesn't seem to have a choice but to expect that maybe AAK hydraulic relief valve can pass the test. A week later, AAK sent out 3 hydraulic relief valve samples. Logan did not dare to send the samples to the customer directly after receiving them, so he had to find a third party for testing before sending them to the customer. Without incident, the customer approved AAK hydraulic relief valve samples. His boss was also surprised that how a hydraulic relief valve manufacturer found by Logan this time can solve the problem so quickly at one time. 

 

The heat treatment process in the early stage is the first step of finishing the size allowance. Most hydraulic relief valve manufacturers adopt local quenching, so the heat treatment process of the workpiece is not easy to control and may be deformed. As early as 6 years ago, AAK adjusted local quenching to overall quenching. At the same time, vertical flow treatment must be required for the hoisting mode in the process of quenching and tempering, so as to minimize the influence of tissue stress and thermal stress on deformation during workpiece heat treatment, so as to meet the requirements of dimensional allowance for finishing.

 

Logan cancelled the order with the original hydraulic relief valve manufacturer without hesitation and confirmed the order with AAK hydraulic valve in two rounds. Logan privately told us that his customers like the hydraulic relief valve manufacturers such as AAK very much. The customer pointed out that AAK should be as the priority supplier for future inquiry of hydraulic relief valves. His boss was also very satisfied with his ability to quickly solve problems this time, and put higher and higher expectations on him.

 

AAK hydraulic relief valves, strictly controls the size allowance of finishing to ensure the accuracy of products. You can also have a small try!
